給たまうN1
ください is the modern, standard way to make a polite request; the suffix 給う (as in its imperative form 給え) serves the same function but sounds archaic and literary.

頂ちょう戴だいplainN3

下くださるN4
くださる is the plain honorific verb meaning 'to give (to me)', while ください is its special imperative form used to make a polite request, so learners must remember to switch to ください (not くださる) when actually asking for something.
お願ねがいいたします
ください directly attaches to a verb to mean 'please do ~', while お願いいたします is a standalone humble formula often used with nouns, as in ご確認をお願いいたします.

Irregular imperative form of the honorific verb くださる (to give). The form ください became fixed as a polite request auxiliary.
